The glass filter is almost always full or above 75% anyway. The extra filter before the pump was to rule out anything coming from the tank.

So far, nothing has been found actually coming through the line. The green crap was found while the tank was off and the fuel strained.

We have concluded this must have come from the tank of the gas station where I gassed up when all this started.

I am going to replace the glass filter with the new plastic one, between the pump and carb.

Paul, your info on the 1/2" line for an electric is useful and will be put to use when I can order the setup I want.

This car is somewhere around 450 HP right now, and I just don't think a stock mechanical pump is adequate.
I know they have high flow mechanicals, but I honestly prefer the consistent volume of the electric, and the control of the regulator to maintain the suggested psi the carb wants.

Heading out to change the filters around as stated, and then change the oil. The needle/seat advise has been ruled out as it would run great for 15-20 minutes before faltering.

It is definitely a fuel delivery issue in the line. Hopefully, as Paul said, removing the extra filter will help. It ran great last night on a test run. Thanks.
